How many bits is a 32 character password?
Random passwords
| Desired password entropy H | Arabic numerals | All ASCII |
|---|---|---|
| printable characters | ||
| 32 bits (4 bytes) | 10 | 5 |
| 40 bits (5 bytes) | 13 | 7 |
| 64 bits (8 bytes) | 20 | 10 |

Why are our passwords so vulnerable to hacks?
Some password-related hacks are beyond our control, but part of our vulnerability is our own fault. We tend to write passwords that are way too easy to guess. And we reuse passwords on multiple websites, so if a hacker has one of our passwords, they’ve got access to other accounts, too.
